Australian rhyming slang for rooted also can be "Wallaby Ted's Brother" (Wallabies and Kangaroo's being closely related). As Kangaroo's are more commonly known as "Roo's" therefore Wallaby Ted = Roo + Ted

Bloke A: What's wrong with your car mate?
Bloke B: Battery has shit itself, it's Wallaby Ted until I can get a new one.
